Adjustment channels

The operating hours counter adds up the solar
operating hours of the respective relay (h P /
h P1 / h P2). Full hours are shown on the display.
The operating hours added up can be reset. As soon
as one operating hours channel is selected, the
symbol is permanently shown on the display.
The button SET (3) must be pressed for approx.
2 seconds in order to get into the RESET-mode of
the counter. The display-symbol
the operating hours will be set to 0, if confi rmed by
button SET within 5 seconds. In order to fi nish the
RESET-procedure, the button
to confi rm.
In order to cancel the RESET-operation, no button
should be pressed for about 5 seconds. The control-
ler returns automatically into the indication mode.
A heat quantity balancing is possible for the basic
systems (Arr) 1, 3, 4 and 5 in conjunction with a
fl owmeter. For this purpose option heat quantity
balancing in channel OHQM has to be activated.
Features:
• guarantees a heat quantity balancing process
during which the two required temperatures close
to the heat exchanger are recorded.
The volume fl ow readable at the fl owmeter (l/min)
must be adjusted in the channel FMAX. Anti-freeze
type and concentration of the heat transfer medium
are indicated on the channels MEDT and MED%.
Type of antifreeze:
0 : water
1 : propylene glycol / antifreeze FS
2 : ethylene glycol
3 : vacuum antifreeze FSV
The heat quantity transported is measured by
the indication of the volume flow and the re-
ference sensor of feed flow S1 and return flow
TRF. It is shown in kWh-parts in the indication
channel kWh and in MWh-parts in the indication
channel MWh. The sum of both channels forms the
total heat output.
The heat quantity added up can be reset. As soon
as one of the display channels of the heat quantity
is selected, the symbol

approx. 2 seconds in order to get into the RESET-
mode of the counter. The display-symbol
fl ashing and the value for heat quantity will be set
to 0, if the button SET is pressed within 5 seconds.
In order to fi nish the RESET-operation, the button
"SET" must be pressed in order to confi rm within 5
seconds once again.
In order to cancel the RESET-operation, no button
should be pressed for about 5 seconds. The control-
